Batch to batch, crust to crust ... In tribute to the beloved staple food, baking master Peter Reinhart reflects on the cordial couplings (wheat and yeast, starch and heat) that give us our daily bread. Try not to eat a slice. This speaker uses humor to give an informational lecture combining food and science. (15:35)

The Peringuey's adder lives in the hot, dry Namib Desert. See how it travels across the burning sand and captures food. In this video, the shovel snouted snake lets heat escape through its lifted feet. Water is a precious commodity. The side winding snake travels across the sand. The snake blends into the sand as it burrows. An unsuspecting lizard becomes lunch for the snake. This is a great teaching resource for elementary/middle school students. It would work well in conjunction with a science lesson on reptiles and/or deserts. This video also helps to build background knowledge (1:59).

From Dragonfly TV. Phoebe and Shannon love exploring Yellowstone National Park. There are so many cool things to see: the canyon, waterfalls, wildlife, lakes, hot springs, and geysers! The girls went to Canyon Visitor Center to learn more about these features-especially the thermal basins, places where there are lots of geysers or hot springs. The park sits on a really big hot spot, made up of magma that rises from deep in the earth. All this magma heats up the ground water in the area and creates thermal features including geysers, hot springs, fumaroles, and mud pots. Geysers are thermal features that have narrow space in their plumbing. Steam forces water through this opening and boom, the geyser erupts! The girls investigate the following question: Why doesn't every thermal basin have a geyser?

This episode discusses the scientific theory of plate tectonics, in which the Earth’s crust is subdivided into a series of large and small tectonic plates. Convergent, divergent or transform boundaries are discussed and demonstrated with brittle graham crackers and icing to illustrate the motions of the plates at these boundaries. A second demonstration consisting of heating cream in a pan, representing convecting upper mantle, driving a relatively brittle layer of cocoa powder (the Crust). (06:02)

Inspirational video showing the benefits of creating green roofs, gardens on roof tops. In this video we look at two of New York's most impressive green roofs to find out how they can help cities cool off and clean up. At a state of the art research station on the roof of Silvercup Studios in Queens, Riverwired's Pulse talks to green roof specialist Leslie Hoffman about how a few plants can reduce water pollution, cool an "urban heat island" by 100 degrees, and improve air quality.

In this video, Pexi the Alien asks Alexi what wind is. Alexi explains that wind is just air that is moving around. It is the uneven heating of the Earth's atmosphere and the cold air/warm air movement causes the wind. Content is appropriate for elementary students. This is a good teaching resource for a lesson/unit/story on weather, climate, and or Earth. (Time duration is not indicated.)

This professionally-made music video from They Might Be Giants explains that a shooting star is actually is a meteor in the sky. Cartoons are simple and cute while the tune and lyrics are catchy and easy to remember. Some lyrics include "A shooting star is not a star, is not a star at all. A shooting star is a meteor that's heading for a fall. A shooting star is not a star. Why does it shine so bright? The friction as it falls through air produces heat and light. A shooting star or meteor, whichever name you like. The minute it comes down to Earth it's called a meteorite." (01:32)

On March 23, 1989, respected chemists, Dr. Stanley Pons and Dr. Martin Fleishman made an announcement that rocked the world of science.
Their tabletop experiments with heavy water, a renewable resource readily available in ocean water, yielded enormous amounts of heat energy. Appropriately named, “Cold Fusion,” this breakthrough challenged many basic scientific concepts.
In response, a group of powerful physicists, heavily reliant upon government funding for their hot fusion research, leveled an unprecedented smear campaign against Pons, Fleishman and the entire field of Cold Fusion science. Was the discovery of Fire From Water too good to be true? Or was it the discovery of the millennium?

Explore the science and beauty of these natural features. Video gives history that the Earth was once an icy ball others believe Earth was cold, but not quite ice. 700 million years ago the Earth was much colder. Volcanoes warmed the surface of the Earth, video shows a volcano that erupted in 2004 where a volcano was filmed erupting through an ice sheet in Central Iceland, this is what would have happened millions of years ago but on a global level. What saved the planet were the tons of carbon dioxide gas. As volcanoes erupted more and more carbon dioxide was released. The layer of carbon dioxide built up and trapped enough heat to end the endless winter. A thaw began and Earth would never be the same. Video is very interesting and is very good quality. Good for elementary grade and middle school students.

The Hydrologic Cycle (or the Water Cycle) is a cycle of evaporation, evapotranspiration, precipitation and infiltration. (02:18)
The sun heats bodies of waters such as oceans and lakes, which causes the water to evaporate and form water vapor. Water vapor is also transpired from trees and soil. The collection of water vapor condenses to form clouds, which move around the globe by air currents. With the right conditions, clouds precipitate; some of the water absorbs into the ground to form an aquifer, and some runs into lakes and streams. This is a continuous cycle, however, human settlement has put a damper on the cycle. For example, industrial waste and toxins can pollute air and water, the building of dams disrupts the natural flow of water, the building of roads cause erosion, to name a few. In order to prevent further harm to the environment, we should consider the consequences of our actions to create a more eco-friendly environment for our future.

The desert biome is characterized by low precipitation, a high rate of evaporation (seven to fifty times as much as precipitation), and a wide daily range in temperature. The dramatic temperature fluctuations are the result of low humidity, which allows up to 90 percent of solar radiation to penetrate the atmosphere and heat the ground during the day, then for this accumulated heat to be released back into the atmosphere at night. Precipitation in deserts, unlike other biomes, is highly irregular. In the Sonoran Desert, rain usually comes in short, sporadic clusters of rainy days three to fifteen times a year. On average, only one to six of these rainfalls is large enough to stimulate plant growth. Thus, Sonoran plants experience long periods of inactivity broken by periods of rapid growth and reproduction. (04:59)

Why did Earth thrive and our sister planet, Venus, died? From the fires of a sun's birth... twin planets emerged. Then their paths diverged. Nature draped one world in the greens and blues of life. While enveloping the other in acid clouds... high heat... and volcanic flows. Why did Venus take such a disastrous turn? (22:08)

This video segment adapted from FRONTLINE: "Heat" examines clean coal technology. It provides statistics for overall annual U.S. consumption as well as average household usage, and then explains the need for developing a cleaner way to convert coal into energy. Visit a Florida energy plant that turns solid coal into a clean-burning fuel gas (syngas), and learn about a new approach to capture and store carbon dioxide gas, a by-product of coal burning. Carbon dioxide is an important greenhouse gas, and each year U.S. coal plants emit 2 billion tons of it into the atmosphere. While promising, most applications of clean coal technology are still not ready for implementation. Closed captioning included. Run time 05:08.
